This publication gathers the lecture notes of classes given on the 2011 summer season tuition in theoretical physics in Les Houches, France, consultation XCVI.

What is a quantum computer? do we say that lasers and transistors are quantum machines? in any case, physicists put it on the market those units because the major spin-offs of the knowledge of quantum mechanical phenomena. despite the fact that, whereas quantum mechanics has to be used to foretell the wavelength of a laser and the operation voltage of a transistor, it doesn't interfere on the point of the indications processed by way of those platforms. indications contain macroscopic collective variables like voltages and currents in a circuit or the amplitude of the oscillating electrical box in an electromagnetic hollow space resonator. In a real quantum computing device, the sign collective variables, which either tell the skin at the kingdom of the desktop and obtain controlling directions, needs to themselves be taken care of as quantum operators, simply because the place of the electron in a hydrogen atom. Quantum superconducting circuits, quantum dots, and quantum nanomechanical resonators fulfill the definition of quantum machines. those mesoscopic structures convey a number of collective dynamical variables, whose fluctuations are good within the quantum regime and whose size is largely restricted in precision by way of the Heisenberg uncertainty precept. different engineered quantum structures in response to average, instead of man made levels of freedom may also qualify as quantum machines: trapped ions, unmarried Rydberg atoms in superconducting cavities, and lattices of ultracold atoms. This ebook offers the fundamental wisdom had to comprehend and examine the physics of those novel structures.

The conventional company of physicists might be schematically regarded as predic­ ting the motions of debris at the foundation of recognized forces, or the propagation of radiation at the foundation of a recognized structure of subject. The inverse challenge is to finish what the forces or constitutions are at the foundation of the saw movement. a wide a part of our sensory touch with the realm round us is dependent upon an intuitive answer of such an inverse challenge: We infer the form, measurement, and floor texture of exterior gadgets from their scattering and absorption of sunshine as detected by way of our eyes. once we use scattering experiments to profit the dimensions or form of debris, or the forces they exert upon one another, the character of the matter is identical, if extra subtle. The kinematics, the equations of movement, are typically assumed to be recognized. it's the forces which are sought, and the way they range from aspect to indicate. As with such a lot of different actual principles, the 1st one we all know of to have touched upon the type of inverse challenge mentioned during this ebook used to be Lord Rayleigh (1877). during describing the vibrations of strings of variable density he in brief discusses the opportunity of inferring the density distribution from the frequencies of vibration. This passage can be considered as a precursor of the mathematical research of the inverse spectral challenge a few seventy years later.
